Non-Thermal emissions from shocked shells driven by powerful AGN jets

Abstract

We explore the emissions by accelerated electrons in shocked shells driven by jets in active galactic nuclei (AGNs). Focusing on powerful sources which host luminous quasars, the synchrotron radiation and inverse Compton (IC) scattering of various photons that are mainly produced in the core are considered as radiation processes. We show that the radiative output is dominated by the IC emission for compact sources (< 30kpc), whereas the synchrotron radiation is more important for larger sources. It is predicted that, for powerful sources ($L_j\sim 10^{47}ergs{s}^{-1}$), GeV-TeV gamma-rays produced via the IC emissions can be detected by the Fermi satellite and modern Cherenkov telescopes such as MAGIC, HESS and VERITAS if the source is compact.
